LUBRlCA-TINGDEVICE.

SPECIFICATION forming part of Letters PatentNo. 629,369, dated July 25,1899.

Application filed May 9, 1898. Serial No. 680,099. (No'modeldspecification.

My invention relates to improvements in lubricating devices, and has forits object the providing of a lubricant-chamber operated by a source ofsteam or other means to deliver to a partto be lubricated predeterminedquantitles of lubricant.

To this end my invention consists of'a lubricator-receptacle arrangedadjacent to the part to be lubricated and a measuring-chamber adapted tobe carried by pressure of steam or other means into position to receivea measore of lubricant from said receptacle and to carry the same to thepart to be lubricated.

My invention further consists in the pare ticular arrangement andconstruction of said parts.

In the accompanying drawings, forming part of this specification, Figure1 is: a partial section .of a steam-cylinder, showing my,

invention arranged in connection therewith. Fig. 2 is a vertical sectionof my lubricator. Fig. 3 is a section on line a: w of Fig, 2, lookingtoward the bottom of the lubricator; and Fig. i is a modifiedconstruction-ofthe main piston.

In the drawings I show one application of my invention, in which Arepresents a steamcylinder, within which works the piston 2, providedwith the ordinary piston-rod 3. Secured in the opening 4: in thesteam-cylinder A is my improved lubricator. This consists of thecylinder-sections 5 and 6, the lower sec-v tion being slidably arrangedwithin the upper cylinder-section and having a screw-threadeddownwardly-extending portion 7, adapted to be threaded in thesteam-cylinder, as shown. Said sections are adj ustably connected bymeans of the clamp G,which consists of rings 8 and 9, solidly connectedby handles 10, said rings being screw-threaded upon the cylinder-sectionsL The lower ring 8 is split, as shown in Fig. 1, andconnected by a bolt 11, by means of which the ring may be tightlysecured in place when the parts have been adjusted to proper positions.

against the flange 31 upon Arranged between the cylinder-sections 5 and6 are packing-rings 12 for the purpose of preventing any leakage of oilthrough the joint between the To further close said joint, I pro videthe ring 13, threaded upon the lower end of the cylinder-section 6 andbearing against thev section 5, and arrange between said ring andsections packing-rings 14. j

Arranged in the chamber 15, centrally cored out of the'cylinder-seotions5 and 6, is the piston D, having an enlarged lower end 16, adapted toabut against the flange '17 upon the upper end of the cylinder-section5, as

2, to limit the upward move- Suitablepacking 18 is arranged in a groovein the periphery of said The upper portion of said piston D is centrallycored out, forming a chamber 19, which holds the quantity of lubricantto be delivered and in which chamber is arranged a piston 20,whichadjusts the capacity be seen by refer- I of said chamber. As will ringto Fig. 2, the upper end'of the piston D is screw-threaded upon the pipe21, which pipe extends through the adjusting-screw 22,

"threaded in the plate 23, secured to the top of the'upwardly-projecting portion 24 of the cylinder-section 6 and held in setposition by A coil-spring 26 is arranged between the adjusting-screw 22and the main piston D, so that by the adjusting 'of said screw thetension of the spring may be varied as may be necessary to secure theproper force of the main pistons Secured in the upper end of the pipe 21is a plug 27, held in set position by a lock-nut 28 and within which isscrew-threaded the rod 29 of the measuring-piston 20.

30 represents the lubricator-reservoir, which is secured in place in themanner shown in Fig.1, the bottomv of the reservoir being formed with anopening through which may be passed the cylinder-sections, the edge ofthe metal adjacent to the opening being held the top of thecylinder-section 6 by means of theclamp O. The reservoir is closed by asuitable cover 32, as shown. The lubricant passes tojthe interior of thechamber 19 by means of the openings 33 through the upwardly-proj ectingportion of the upper cylinder-section and the openings 34 through theWall of said chamber. The space below the piston 20 will be filled bythe lubricant, so that the height of the piston will determine thequantity of lubricant which may be held bythe chamber. A conduit 35connects the upper end of the mainpiston chamber 15 with the part to belubricated.

The operation of my improved lubricator is as follows: The lubricator isproperly secured to the steam-cylinder or other part, as shown inFig. 1. As the piston 2 travels from the lubricator the live steamentering the cylinder will enter the chamber 15 of thelubricator,raising the main piston D to the position shown in Fig. 2. The lubricantwill then pass through the openings 33 and 34 to the interior of themeasuring-chamber 19. As the steam-pressu re falls in the oppositetravel of the piston in the steam-cylinder the spring 26 will force thepiston D of the lubricator to lowered position. This will bring theopenings 34 of the measuring-chamber below the flange 17 at the upperend of the main-piston chamber 15. Since the portion of the piston Dabove the head 16 is of smaller diameter than the chamber 15, therewould be a surrounding space when said piston is in lowered position,into which space the lubricant from the chamber 19 will run by gravity.The next movement of the piston in the steamcylinder will raise thepiston D of the lubricator, and as the openings 34 are carried above theinwardly-projecting flange 17 the continued upward movement of thepiston will force the lubricant through the conduit to the part to belubricated. The above described operation of the parts is kept up aslong as there is any travel of the piston in the steam-cylinder.

From the foregoing description it will be evident that the parts can beset to measure and deliver any desired quantity of lubricant, and thatafter being set the operation is automatically maintained by thesteampressure Without any attention to the lubricator being necessaryuntil the reservoir has been emptied of its contents.

While I show the parts operated by steam, it will be evident that othermeans may be used for operating the .same. It also is possible to usewith my device solid lubricants, since the steam will so heat up theparts that the solid lubricant will be melted and carried to the partsto be lubricated in liquid condition.

In Fig. 4 I show a modified form of piston. A piston of thisconstruction is intended to be used in order to adapt the lubricator todeliver lubricant either through the conduit 35 or the opening 4 in thesteam-cylinder. When itis desired to deliver the lubricant through theopening 4, the conduit 35 is plugged up and the plug removed from theopening 37 in the piston D. The lubricant will then pass through saidopening as the piston D is raised and through the openi'ng4 in thesteam-cylinder.

I claim- 1. In an apparatus of the class described, the combination witha lubricant-reservoir, and a part to be lubricated, of a chamberedpiston arranged intermediate of said reservoir and steam under pressure,and adapted to be carried by said steam into position to receive ameasure of lubricant from said reservoir, means for carrying said pistoninto position to permit the containedlubricant to pass to a secondchamber, said piston being actuated by the steam under pressure to forcethe lubricant from the second chamber through suitable conduits to thepart to be lubricated.

2. In an apparatus of the class described, the combination with alubricant-reservoir and the part to be lubricated, of a device arrangedintermediate of said reservoir and steam under pressure, acontrolling-spring for said device, said device being actuated by steamunder pressure against the tension of said spring to receive a supply oflubricant, and to be similarly actuated against the ten sion of saidspring to force said supply through suitable conduits to the part to belubricated. g

3. In an apparatus of the class described, the combination with thelubricant-reservoir, and the part to be lubricated, of the chamberedpiston arranged intermediate of said reservoir and steam under pressure,and adapted to be carried by said steam into position to receive apredetermined quantity of lubricant from said reservoir, the means foradjusting the size of said chamber, and the means for carrying saidpiston into position to deliver the contents of said chamber to saidconduit upon the decrease of the steampressure. r

4. In an apparatus of the class described, the combination with thelubricant-reservoir and the part to be lubricated, of a piston providedwith a chamber, means for adjusting the size of said chamber, and meansfor actuating said piston to bring said chamber into communication withthe contents of said reservoir, and thereafter into position to deliverits contents to the part to be lubricated.

5. In an apparatus of the class described, the combination with thelubricant-reservoir and the part to be lubricated, of a piston providedwith a chamber, a second piston ad justably arranged in said chamber forvarying the capacity thereof, and means for actuating said first pistonto bring said chamber into communication with the contents of saidreservoir, and thereafter into position to deliver its contents to thepart to be lubricated.

In testimony whereof I affiX my signature in the presence of twowitnesses.
